Try attaching gdb to see where it hangs.
(gdb) run
Starting program: /usr/local/bin/gpg --list-keys
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
[Detaching after fork from child process 41865]
^C
"gpgconf --kill all" solved my problem, but I'd still advise y'all to
look into where it got wedged and why -- this was an incredibly annoying
problem to solve, and the total lack of debugging output elevated it to
tremendously frustrating.
